  HVLP spray gun is a kind of pneumatic spray gun with high air velocity(5-18 CFM) and low pressure ( 10-30 PSI), which is more common in life, such as (rongpeng H-827B, rongpeng 1020,  etc.). So as for why it is so popular, take this Rongpeng 1020 (4.2-7.1cfm, 2.0-3.5bar) and Rongpeng R807(4.2-7.1cfm, 2.0-3.5bar)as an example, let's explore it together.
Coatings

HVLP paint gun is suitable for many types of low-viscosity coatings, such as clearcoats, metallic paints, water-based base coats, etc., such as automotive body painting, furniture painting and architectural coating. For example,the rongpeng H-827B nozzle and needle are made of stainless steel, which has good corrosion resistance and durability. For different types of paints, it is not easy to be corroded or damaged, thus ensuring the long-term performance of the spray gun.

High paint utilization
If you are an auto repair shop owner or the owner of a family, then the cost and utilization rate of paint is definitely one of your considerations. The utilization rate of rongpeng hvlp spray gun 1020 is as high as 65%, which means that at least 65ml of 100ml of paint is finely atomized and evenly attached to the surface of the object to be sprayed, and rongpeng1020 uses a standard 1.4mm diameter nozzle, and a smaller diameter nozzle can also atomize the paint more finely to form a high-quality and uniform paint layer. For example, it may be more intuitive, that the utilization rate is only 30% of the spray gun, the capacity of a bucket of paint is 300ml, and Rongpeng 1020 can reach a utilization rate of more than 195ml, while ordinary spray guns are only more than 90ml, the difference is more than twice as much; The high paint utilization rate also reduces overspray and paint rebound, which reduces the subsequent cleaning cost and environmental pollution

Choose the caliber according to the scene
HVLP spray gun can be suitable for small workpiece spraying can also be applied to large workpiece, the larger the nozzle diameter, the larger the spraying particles, the higher the spraying efficiency for large areas, but it is easy to produce overspray, poor atomization effect and other problems, the smaller the nozzle diameter, the better the atomization effect, the finer the spraying, but the efficiency is lower. Take Rongpeng 1020 as an example, the standard diameter of RPNGPENG 1020 is 1.4mm, providing 1.3-2.5mm nozzles, 1.3 and 1.4mm diameter nozzles belong to smaller diameters, suitable for furniture surfaces, toys, decorations, car touch-ups, etc.; The 2.5mm diameter nozzle is suitable for large-area spraying tasks, industrial coating, chemical equipment spraying, etc.
